But unlike Snapchat, these pictures don’t disappear in ten seconds. They can last a lifetime. You can consult Anthony Weiner to see if that is a good idea.

While nudity and spam already abound on Instagram, even though it’s against the rules, you had to follow someone to see those images. Now they come to you! (Although you do have to approve a post request from someone who you don’t already follow and block them if you didn’t like what you saw… and never ever ever want to see it again.)

Instagram suggests, “Ignore people you don’t want to hear from. If you want to ignore all messages from someone you follow, you can always tap the “. . .” in your direct posts and select the option to Ignore All from that person.”
